Special Containment Procedures
SCP-XXXX is to be kept in a cell that is to be constructed from reinforced concrete. The cell is to be checked by maintenance for any signs of cracks on a weekly basis. Should any organisms come into contact with SCP-XXXX they are killed by a nerve agent. Should the nevre agent fail 05 command is to enter SCP-XXXX's containment chamber and terminate any instances of SCP-XXXX-1. As any contact with SCP-XXXX may result in [DATA EXPUNGED] and the organisms will turn into SCP-XXXX-1 Access to SCP-XXXX and its containment chamber is restricted to controlled testing with authorization of the Site Director.

Description
While in a dormant state SCP-XXXX will appear to be an ordinary boulder however it isn't. The creature is approximately 1.5 meters in diameter. When SCP-XXXX is disturbed it will grow 10 legs each approximately 1 meter in length. In total SCP-XXXX weighs roughly 1.2 metric tons. And is capable of moving at speeds of █ kilometers an hour to █ kilometers an hour. When SCP-XXXX is exposed to any organism larger then approximately 1.5 millimeters, the organism will undergo [DATA EXPUNGED] and will turn into SCP-XXXX-1, an identical copy of SCP-XXXX. However, said organism retains their original size. When a subject is exposed SCP-XXXX at a distance of 5 meters from SCP-XXXX. SCP-XXXX will change the neurological structure of the subjects brain. Individual neurons will fire not as the subject, but as SCP XXXX. This enables SCP-XXXX the ability to communicate with foundation personnel using our language. How it does so is unknown.
